Abstract: Under the significant influence of the RCEP Agreement, Yunnan’ s coffee industry urgently needs to enhance its international competitiveness and achieve transformative development. This study combines grounded theory and quantitative analysis to build a multi - dimensional framework. It uses indices like RCA, TCD, and QC for quantitative analysis and a multiple regression model to explore the factors affecting export quality upgrade.The results show that international futures price fluctuations and RCEP’ s mature - stage policy dividends drive the export quality upgrade of Yunnan coffee. However, regional competition and exchange - rate - transmission lags limit its development. Currently, Yunnan’ s coffee industry has issues such as high planting costs, weak international competitiveness, and low regional - trade participation, and trade complementarity fails to boost quality upgrade. In response, this study suggests countermeasures like an “insurance + futures” risk - hedging mechanism, deep - processing industrial clusters, and an industrial database. These aim to transform the industry from “scale expansion” to “quality leap” , providing theoretical and practical support for integrating border agriculture into the regional value chain and upgrading the industry.
